Preheat oven to 350°F.
Season spinach with salt to taste.
Put into oiled, 2 quart casserole.
Sprinkle with cheese.
With the back of a spoon, make 6 little wells, evenly spaced, about 1 inch deep, on the surface of the spinach.
Break a raw egg into each well.
Bake in preheated oven until the eggs are set (about 8 minutes).
